Chain of Command(2000) [Iris]: Garroted with a steel cable by Phillip Tan while she's buying time for Patrick Muldoon. (Thanks to Anonymous and Eric)

Death to the Supermodels(2005) [Hoo Chi a.k.a. Hung So Lo]: Neck snapped with a kick to the head at the end of a fight with a ninja in the woods. (The killer was played by T.J. Storm during the actual murder, but was later revealed to be Diane Delano in disguise.) Her body is shown afterwards when the others discover her; after her death, her character is revealed to be a pre-operative transsexual when the others notice that she has an erection. Still later, there's a lengthy sequence of her body being propped up and posed so that Jaime Pressly, Taylor Negron, and Matt Winston can complete the photo shoot. (Played for comic effect, obviously.)
